Prediction markets put the probability at 56%: Will Avengers: Doomsday have the best domestic opening week in 2026. Currently, markets are divided (56% YES, 44% NO).
The question of whether Avengers: Doomsday will have the best domestic opening week in 2026 hinges on a bar that rivals set earlier in the year. Disney moved Avengers: Doomsday out of its traditional late-April/early-May slot to December 2026, ceding the summer superhero window and leaving Lionsgate's biopic Michael ($210 million in May) to fill the gap. That shift means the film now competes against a full year of releases already on the board, including the highest-grossing debut of the year to date. [TheWrap, Jun 01]
The benchmark to beat is steep. Spider-Man: Brand New Day opened to an estimated $355 million domestically over its debut weekend, the second-best opening ever and just shy of Avengers: Endgame's all-time record $357.1 million. The film crossed $1 billion worldwide in just six days, and the frame helped push the 2026 box office up 15.2 percent year-over-year. For Avengers: Doomsday to have the best domestic opening week in 2026, it would need to clear that towering Spider-Man figure, not merely the prior high of Toy Story 5's $159.6 million.

History offers Marvel a case for optimism: Avengers titles hold three of the top openings ever, with Infinity War at No. 4. The industry is tracking tentpoles including Dune 3 and Avengers: Doomsday to lift 2026 domestic revenue, with May-to-early-August grosses already at $3.579 billion. Whether Avengers: Doomsday can have the best domestic opening week in 2026 will depend on its December release landing above Spider-Man's record-adjacent debut, a threshold no film has matched since Endgame in 2019.
